Modular storage box

ABSTRACT

A modular storage box, comprising a base, a first and a second walls, and a lid, capable of increasing its capacity longitudinally by way of the connection, by way of bridge elements, of additional first walls and second walls and bases, the bridge elements being mutually connected by a cross-member, all of the components being connected by way of reversible interlocking elements.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a modular storage box.

[0002] Modular storage boxes are currently known which are composed of a base with which two longitudinal walls and two side walls are associated, each longitudinal wall being fixed to the two side walls and each side wall being fixed to both longitudinal walls.

[0003] The modular storage box is completed by a lid that is hinged to one of said walls.

[0004] The base, the walls and the lid are mutually connected by way of detachable connection means.

[0005] Such detachable connection means are of the type with reversible interlocking; the walls, the base and the lid are therefore particularly easy to assemble/disassemble even for a user lacking particular technical skills.

[0006] Under the base there are castors that allow to move the storage box easily even in the assembled configuration.

[0007] Such storage boxes are very useful because of their capacity in every room of a house, from bedrooms to bathrooms to the garden.

[0008] Such storage boxes have a wide market owing to their great versatility, light weight, easy handling and therefore easy transport, and to their low cost.

[0009] The modularity of the storage boxes is a great advantage for manufacturers and retailers, who can package and store the modular storage boxes and to optimize the space available.

[0010] The modular storage boxes as described above, although being commercially known for several years, have perfectible aspects.

[0011] One drawback is that they can be assembled according to a single assembly method.

[0012] An equally important drawback is that such storage boxes are limited longitudinally due to the inherent limits of the molds and machines employed for molding.

[0013] Molds of exceptional size in fact entail an exponential cost increase, arising both from the size increase and from the increase in the problems linked to the molding techniques and methods employed.

[0014] This drawback generally conditions the capacity of the storage box, in particular by not allowing to store therein all garden maintenance or house cleaning tools that are particularly long, such as vacuum cleaners, string trimmers, rakes and many others.

SUMMARY OF THE INVENTION

[0015] The aim of the present invention is to provide a modular storage box that allows a wider public offer range.

[0016] Within this aim, an object of the present invention is to provide a modular storage box comprising components that allow to increase the capacity of the storage box.

[0017] Another object of the present invention is to provide a modular storage box that can be manufactured with known technologies and systems without resorting to molding machines that have special dimensions and are therefore particularly expensive.

[0018] An important object of the present invention is to provide a modular storage box whose components can be packaged and stored easily, optimizing the space available.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] With reference to the figures, a modular storage box according to the invention is designated by the reference numeral 10 in this case.

[0038] The modular storage box 10 comprises two bases 11, one of which is provided with two castors 12 below one of its lateral edges 13.

[0039] A first wall 15 and a second wall 16 are associated on the longitudinal edges 14 of each base 11 by way of detachable connection means 31.

[0040] A lid 18 is connected to each one of the second walls 16 by way of detachable connection and articulation means 17.

[0041] The first and second walls 15 and 16 have, on their vertical edges 19, first engagement means 20 for connection to additional components described in greater detail hereinafter.

[0042] The first engagement means 20 are constituted by lugs 20 a that are monolithically associated with the vertical edges 19.

[0043] Each lug 20 a comprises a flexible chamfered stud 20 b.

[0044] The lugs 20 a with studs 20 b interlock reversibly in corresponding and suitable contoured centering and connection portions 21, which are provided in the facing components that are described in greater detail hereinafter.

[0045] The bases 11 have, on their lateral edges 13, complementarily shaped seats 22 that are suitable to accommodate second engagement means 28 and third engagement means 30 that protrude downward from said components and are described in greater detail hereinafter.

[0046] The first engagement means 20 and the complementarily shaped seats 22 allow the first walls 15 and the second walls 16 and the base 11 to connect components selected at will between bridge elements 23 and side walls 24.

[0047] The bridge element 23 is monolithically constituted by a vertical portion 25, by a footing 26 and by a substantially triangular element 27 for reinforcement and connection between the vertical portion 25 and the footing 26.

[0048] The bridge element 23 comprises laterally the contoured centering and connection portions 21, and the second engagement means 28 protrude below the footing 26.

[0049] The second engagement means 28 are constituted by first tabs 28 a with an engagement tooth 28 b.

[0050] The first tabs 28 a, and therefore the teeth 28 b, are monolithic with the footing 26.

[0051] The third engagement means 30 protrude from the lower sides 29 of each one of the side walls 24.

[0052] The third engagement means 30 are constituted by second tabs 30 a, with engagement teeth, which are monolithic with the lower sides 29 and therefore with the side walls 24.

[0053] The first tabs 28 a and the second tabs 30 a are flexible and engage by reversible interlocking in the complementarily shaped seats 22 on the lateral edges 13 of the bases 11.

[0054] Contoured centering and connection portions 21 are also provided on the side walls 24.

[0055] The two bridge elements 23 allow, by means of the first tabs 28 a, the connection between the two mutually adjacent bases 11 by means of one of their lateral edges 13, and allow, by means of the contoured portions 21, the engagement of two of the first and second walls 15 and 16.

[0056] The two side walls 24 complete the configuration of the storage box 10, being arranged on the sides of the structure that are not occupied by the bridge elements 23.

[0057] The detachable connection means 31 are constituted by third flexible tabs 31 a provided with an anchoring tooth 31 b.

[0058] The third tabs 31 a protrude monolithically from the lower edges 32 of the first and second walls 15 and 16 and engage by reversible interlocking in slots 33 that are shaped complementarily on the longitudinal edges 14 of the bases 11.

[0059] The bridge elements 23 are mutually connected by a cross-member 34.

[0060] The cross-member 34 has T-shaped ends 34 a, each of which is suitable to be accommodated in a corresponding complementarily shaped cavity 35 that is provided above the vertical portion 25 of the bridge element 23.

[0061] The cross-member 34 comprises a drainage channel 36 that runs longitudinally with respect to said cross-member 34.

[0062] The cavities 35 are shaped so as to form a raised edge 35 a for preventing overflow.

[0063] The vertical portion 25 of the bridge element 23 has a drainage opening 37 at the upper end of the outside wall.

[0064] The drainage channel 36 and the opening 37 allow, if the box is placed outdoors and exposed for example to rain, the water to be captured directly below the slot provided between the two adjacent lids 18 and to be expelled rapidly, therefore avoiding the penetration of the water in the box, wetting its contents.

[0065] The raised edge 35 a acts as a barrier to any seepage of drained liquid that penetrates between the T-shaped end 34 a and the respective cavity 35.

[0066] The cross-member 34, arranged in a beam-like fashion, prevents the bridge elements 23 from flexing outward (due to any pressures applied by the content of the storage box to first and second walls 15 and 16), further improving the interlocking of the lugs 20 a with the contoured portions 21 and the strength of the structure in general.

[0067] The modular storage box 10 comprises a complementary element 38, which is provided with detachable, complementary connection means 39 for connection to the adjacent lateral edges 13 of bases 11 that are connected by means of the bridge elements 23.

[0068] The detachable connection means 39 are constituted by fourth tabs 39 a, which protrude monolithically downward from the lower face of the complementary element 38.

[0069] The fourth tabs 39 a are flexible and have an anchoring tooth 39 b at their end.

[0070] The fourth tabs 39 a interlock reversibly in the seats 22 that are shaped complementarily on the lateral edges 13 of the bases 11.

[0071] The complementary element 38 strengthens the coupling between the bases 11 already provided by the bridge elements 23 and improves the design of the interior of the storage box.

[0072] Proximate to the first tabs 28 a, the second tabs 30 a, the third tabs 31 a and the fourth tabs 39 a centering and reinforcement elements 40 are provided, which enter complementarily shaped holes 41 provided in the lateral edges 13 and longitudinal edges 14 of the bases 11.

[0073] The centering and reinforcement elements 40 facilitate assembly and make the assembled structure less likely to splay (due for example to any pressure generated by the contents of the storage box) in the connection regions.

[0074] The two lids 18, which complete the storage box 10 in an upper region, are connected by way of detachable articulation and connection means 17 to the respective second walls 16.

[0075] The detachable articulation and connection means are constituted by plate-like elements 17 a, which rise vertically and monolithically from the second walls 16 and have pivot elements 17 b at their ends.

[0076] The plate-like elements 17 a and the pivot elements 17 b are flexible and interlock reversibly in the complementarily shaped seats 17 c formed below each one of the lids 18 at one of the longitudinal sides.

[0077] The modular storage box 10 assumes a basic configuration 42, which comprises one of the bases 11, two of the castors 12, one of the first walls 15 and the second walls 16, one of the lids 18, and two of the side walls 24.

[0078] The modular storage box 10 assumes a combined configuration 43 if it is composed of two of the bases 11, two first walls 15 and second walls 16, two lids 18, two side walls 24, two bridge elements 23, a cross-member 34 and a complementary element 38.

[0079] In practice it has been found that the intended aim and objects of the present invention have been achieved.

[0080] In particular, it should be noted that the modular storage box 10 according to the invention, in its combined configuration 43, has twice the capacity of the basic configuration 42, while maintaining the same characteristics of light weight, strength, easy handling and adaptability to any kind of environment.

[0081] In practice, the materials employed may be any according to requirements, so long as they are compatible with the contingent use.
